PR Cleanup Skill

Overview

This skill provides safe, systematic cleanup of local branches after PR merge. It implements a Sequential Safety pattern: identify target, verify merge status, delete safely, confirm result. The workflow follows 5 sequential steps to prevent data loss and ensure reliable cleanup.

# List worktrees referencing any branch
git worktree list
